Abstract

An optical fiber includes a coating comprising a cross-linked network comprising the reaction product of monomers and oligomers and at least one polymer dispersed or interpenetrated in the cross-linked network. The oligomer and polymer components used are at least partially fluorinated. The fiber-coating composition of the invention presents a refractive index that is low while satisfying the conditions for industrial fiber-drawing.
